Gyokuhokan (玉峰館) is a ryokan in Kawazu, Izu that has been running since 1926 on kakenagashi spring water, meaning the baths flow continuously without recirculation. The centerpiece is a large communal rotenburo built into rock, plus an indoor bath and three private kashikiri (貸切) baths that guests can reserve free of charge. Some rooms come with their own open-air bath. The ryokan sits next to Mine Onsen Daifunto Park (峰温泉大噴湯公園), a geyser park, and serves kaiseki meals in the evening.
